Abstract

A thermal print head comprises a head base plate (11) formed of an insulating material, a heating element (12) provided along a side edge of the head base plate, a drive IC (13) for driving the heating element, a temperature sensor (18) provided on the head base plate for monitoring a temperature of the heating element, and a radiating member (20) secured to the head base plate. The radiating member has a first surface for fixing the head base plate, and a second surface corresponding to the temperature sensor, the second surface facing and spacing from the head base plate to define a heat transfer performance regulating area (22). The head base plate and the radiating member are fixed to each other by means of an adhesive member (21) which has a desired heat transfer performance.
